## Abstract Resonant electronic transport through two coupled nonβinteracting singleβlevel quantum dots attached to ferromagnetic leads with collinear magnetizations is analyzed theoretically. Coupling of the dots to external leads as well as the interβdot coupling are assumed to be spin dependent.
## Abstract In this work, we study the effect of an applied ac gate voltage on the spin filtering and pumping properties of a lateral double quantum dot, in the Coulomb blockade and weak coupling regimes, considering not only the effect of the ac potential on the interβdot tunneling but also on the
